Identifying silver(plate?) maker
Wondering if someone knows what/how to decipher this mark. Have checked 'A', 'DC', and 'ADC' to no avail. Hoping the rest of the marks may give up more clues.
The piece is a tiny spoon, 3-3/4", with a cut-out thistle decoration on top. These markings are on the outer edge face of the bowl, not where one usually finds these markings.
